M8427
M8196: the activation flag of using programming port protocol and other protocol
(Main version 26232 and
higher, modified to not maintain power failure).
M8125: the activation flag of using MODBUS and the original Mitsubishi function.
M8122: Send flag (this bit needs to be set 1 when using the RS instruction).
M8123: Communication completion flag (communication completion flag when using RS command, needs
to be reset by hand).
M8161: 8-bit/16-bit mode distinguishing flag for RS/RS2 instruction (used in version 26230 and above,
always in 8-bit mode in versions 26210 and 26220)
M8128: Communication completion flag (valid when using RD3A and WR3A for MODBUS
communication, needs to be reset by hand).
M8029: Communication completion flag (communication completion flag when using ADPRW instruction,
needs to be reset by hand).
D8120: Save the communication parameters of the Modbus RTU protocol, and the highest bit of the
communication parameters must be set to E.
D8121: Save the host or slave station number.
D8129: RD3A and WR3A time-out period. (Unit: ms. Better not over 100ms while setting).
D8126: When using the serial port 2 in the ADPRW instruction, set D8126 to 0.

。
Parameter zone settings are valid only for this channel. Invalid for serial port 3.
2.11.1.1 Mitsubishi programming port protocol
When used as programming port protocol: set M8196=0.
2.11.1.2 Free port protocol
When used as MITSUBISHI protocol: set M8196=1
,
M8125=0
;
the difference between Mitsubishi
protocol 1 and protocol 4 is with end mark OA OD ( stored in D8124, D8125 separately)
2.When used the Mitsubishi protocol, the D8120 only needs to set the lower 8 bits.
